What is the significance of stem cell research?

• It has the potential to lead to breakthroughs in regenerative medicine and treatments for various diseases.

• It is primarily used for cloning animals.

• It has no real-world applications and is mostly theoretical.

• It is only relevant for cancer research.

What is the role of stem cells in tissue repair?

• Stem cells can differentiate into the necessary cell types to repair damaged tissues.

• Stem cells are primarily involved in the production of hormones.

• Stem cells only exist in embryos and have no role in adults.

• Stem cells are responsible for the immune response in the body.

Where can stem cells be found in the human body?

• Skin, liver, muscles, intestines, and bones

• Heart, lungs, kidneys, and brain

• Nails, hair, and teeth

• Blood, saliva, and sweat

What is the difference between embryonic and adult stem cells?

• Embryonic stem cells are multipotent and adult stem cells are pluripotent.

• Embryonic stem cells can become any cell type, while adult stem cells have a more limited differentiation potential.

• Adult stem cells can become any cell type, while embryonic stem cells are usually multipotent.

• Embryonic stem cells are only found in adults, while adult stem cells are found in embryos.

What does 'differentiation' mean in the context of stem cells?

• The process by which stem cells develop into specialized cell types.

• The process of stem cells dividing into more stem cells.

• The process of stem cells being destroyed by the immune system.

• The process of stem cells migrating to different parts of the body.

What does it mean for a stem cell to be multipotent?

• Multipotent stem cells can divide and differentiate into multiple, but not all, types of cells.

• Multipotent stem cells can only divide into one type of cell.

• Multipotent stem cells can differentiate into any type of cell in the body.

• Multipotent stem cells are unable to divide or differentiate.

What are induced pluripotent stem cells (iPSCs)?

• Adult cells that have been genetically reprogrammed to an embryonic stem cell-like state.

• Stem cells derived from embryos only.

• Cells that can only differentiate into one type of cell.

• Adult cells that cannot be reprogrammed.
